Catch exceptions in YAML menus

* lib/mudpy/misc.py(Element.facets,Element.get): Early in login and
account creation, elements can have None in place of a dict for their
data. Under these circumstances, listing their keys throws
AttributeError and deep-linking into specific keys throws TypeError.
Catch these and treat them as empty.
